So I have been getting spam emails from AT&T lately. I login to the site and it seems there everything is opted out. Call customer support, will not bother with such a joke, straight to BBB resolution process. And AT&T calls me says everything seems ok. They call me back and tell me:
When you out out of AT&T spam it is only for 3 years, so because it expired you need to opt out again.
How to do it? Unknown, AT&T resolved it for me.
Example AT&T Spam Subject: See your myAT&T account and device how-tos
